swun back to osition without disturbing the a ustment.

These and other objects and features of the invention willappear more fully from the accompanyin description and drawings and will be particularly pointed out in the claims.

Two forms of the device embodying the broad principles of the invention but differing in specific features are illustrated.

In the drawings:

Fig. 1 is a front elevation of one form of the device embodying the preferred form of the invention.

Fig. 2 is a rear elevation of the construction. shown in Fig. 1.

Fig. 3 is a side elevation of the same construction looking toward the right of Fig. 1.

Fig. 4 is a front elevation of another form of construction.

Fig. 5 is a rear elevation tion shown in Fig. 4.

Fig. 6 is a side elevation of the same construction looking toward the left of Fig. 4.

The construction illustrated in Figs. 1 to 3, inclusive, includes a two-part bracket supporting the various elements of the yarn cleaner and which is ada ted to beclamped to the usual traverse rod l of a spooler or similar machine. The main part 2 of the bracket andthe clamping part 3 are each provided with substantially semi-circular transverse recesses facing each other and adapted to embrace the traverse rod. Flange portions 4 and 5 depend from the bracket parts and are secured together by a clampmg bolt 6 so that when the bracket is in place on the traverse rod, the bracket parts are rigidly secured together and rigidly secured to the traverse rod.

A toothed comb is employed for removing the slubs, etc., from the yarn and the of the construcyarn in its passage through the comb is guided over a main ide rod 7 and an auxiliary guide rod 8, oth of which are se-' cured to and project laterally from the main bracket part 4, both herein shown as driven into holes formed in the bracket.

In this type of device it is necessary that the line of comb teeth be accurately spaced from the main guide rod 7, that the line of the comb teeth be parallel to the main guide rod, that suitable provision be made for varying as required the space between the line of comb teeth and the main guide rod, and that provision be made for Swingin the comb member away from the guide roc to permit the cleaning of the comb or the removal of the slubs, etc., therefrom and then for returning the comb member to operative position without disturbing any of the adjustments.

The comb member, in the form under consideration, is shown as comprising, first, a flat blade 9 extendin generally parallel with the guide rod and aving a rearwardly bent or formed ear 10 and, second, a comb proper shown as a flat plate 11 fitting agalnst one face of the blade 9,and provided at its lower edge with a row of comb teeth 12. In the construction illustrated, the blade 9 normally stands substantially vertical and consequently the lower edge of the plate 11 is bent forwardly and downwardly as shown at 13, so that the comb teeth may resentthe angle required. to allow the slu s, etc., to-slide up thereon during the passage of the yarn. The comb plate-11 1s ivoted at one end on the bolt 14 to the p ate 9 and means are provided at the other end for adjustably securing the comb to the blade. For this purpose the comb plate is provided with an enlarged opening 15 fitting over a bolt 16 passing through the blade 9.

The bracket part 2 is provided at the rear with a vertical y split extension 17 having a vertical cylindrical bore and at the rear thereof a transverse clamping bolt 18. A comb member support is provided having a cylindrical shank 19 fitting this bore and a head 20 vertically slotted to receive the ear 10 of the blade 9. A pivot screw 21 passing through the head 20 and the blade 10. ermits the comb member to swin into and out of cooperation with the gui e rod 7. The downward swinging movement of The vertical pivotal adjustment of tliecomb piste ll on the blade 59 enables the line of comb teeth to be sdiusbed to vertical porollelism wit-l1 ilie guide rod l.

it will thus be seen ibot any required udiustment may be accurately and readily made and tbsb the comb member may be swung upwardly on the pivot 21 lo permit the cleaning of the comb and then return in operative position WlillOlliJ disturbing ilie adjustment. Furthermore, if the comb ieetli become broken or damaged, as new comb plate may resdily be substituted.

in Figs, l to 6, inclusive, another form oi device is illustrated embodying certain leetures of the invention. in this construction the bracket comprising the main port 23 end the clamping port 24- secured to blie "troverse rod 1 by the clamping bolt, 25 is substentielly the some us that already described. The comb support has s similar cylindrical shank 26 clamped by the bolt 2'7- in the split reurwsrd extension of the bracket, but in this case the bead 28 of the support is pro vided at the front with s rearward end upward inclined face 29 normally extending parallel to the guide rod 30. Upon this in clined face is pivoted the comb member, which in this case is s, single blsde 31 pivcred on the screw stud 32 extending into the bead 29. This plate is provided at its lower vedge with a row of comb teeth 33 end as the blade is inclined, the comb teeth are, properly inclined with respect to the guide rod. The vertical ed'ustment end roiery adjustment of rho comb in the bracket are secured in the same manner as alreudy described.

The comb member in this case is swung upwardly on the pivot 32 to permit the cleaning of the comb and downwardly to bring it inlo operative position. Adjustable means are provided in this case for limiting the downward swinging movement of the comb and are herein shown as a set screw 34 threaded through 35 in the bracket, abutting the edge of the blade 31 and locked in adjusted position by the lock nut 38. This adjustment not only limits the downward movement of the comb member, but also enables it accurately to be positioned in verticol arallelism with the guide rod 30, A pin 3'? in the comb member 31 limits the up word swinging movemenb thereof support on its verticsl axis 'i'rom the bracket The comb member is preferably beld its normal operative position sgsinsf: the se 1 screw 34: by e sprin The operative me readily swing the comb member is clean osition against the tension of this sprin out this spring insures automatic return o the comb member'to operative position. A

suitable belicsl spring for this purpose is shown at 38 seated in the bead 29 surrounding the screw stud 32 and engag ng at one end tlie bead and at the other end the comb member.

, rod.

Having thus described the invention, wliet is claimed as new, and desired to be secured swinging movement of the comb member,

7. A arn cleaner for spoolers and similar mac ines comprising a bracket, a guide rod projecting laterally therefrom and over which the yarn passes, a support carried by the bracket and both vertically adjustable with respect thereto and rotarily adjustable on its vertical axis, and a comb carried by the support and adjustable with respect thereto to bring its teeth into vertical parallelism with the guide rod.
